more pragma strict getComponent and SendMessage problems

I have a many game objects with many scripts attached during runtime. The user chooses which script to attach to which gameObject.

Without pragma strict I change properties and run functions on those scripts from the main script and it works fine. With pragma strict nothing works.

Here's what I've tried so far and the errors I get with

 #pragma strict;
 
     function changeSomething(go:GameObject,script:String){
     go.GetComponent(script).initialize();//doesn't work
     var prop=go.GetComponent(script).somepropertyinscript; //does not work either.
     go.SendMessage("initialize"); //works
     var test=go.SendMessage("getProperty"); //doesn't work
 }

SendMessage cannot return a value???

Right now nothing works..I could make a different function for every possible combo of gameObject and script but that may be 50 functions if I have 5 gameobjects and 4 script choices each? Or I could move everything into one script?

Is there a better way to go about talking to scripts with pragma strict?

Thanks,
